This means identifying holes on the roster, and figuring out how to plug those holes. Free agency is certainly one way to go for the San Francisco Giants.
The Giants, like most teams, have been burned in free agency. The slow market last offseason was due in part to the players available. However, it was also due to many of the contracts becoming albatrosses by the end of the deal.
As a result, teams were unwilling to meet contract demands in terms of length of time. If the players do not change their demands, then we may see another slow offseason.
